(C++ code)

int main() { int num1 = 2; int num2 = 5; int num3;

if (num1 > 0 && num2 > 0) num3 = num1 + num2; else if (num1 > num2) num3 = 0;

return 0; }

Answer the following 2 questions (1pt each): a. Is the logic (or branching decision) of the if statement in assembly, including the nested if part, as efficient as it could be? If yes, explain why by typing your short explanation in the textbox. If no, "fix" the compiler's assembly code by copying in the inefficient part, and then type in how you would write the assembly code.

b. Is the rest of the code (not counting the if statement) as efficient as it could be? If yes, explain why by typing your short explanation in the textbox. If no, "fix" the compiler's assembly code by copying in the inefficient part, and then type in how you would write the assembly code.
